Choose your starting point

What kind of IRS issue are you facing?

The right response depends on the notice, deadline, whether action has begun, and whether the underlying return or balance is correct.

A Form 1040, a W-2, and a U.S. Treasury check on a desk.
01

I received an IRS notice

Find out what the code means, which deadline is running, and whether the IRS is asking for payment, documents, or a correction.

Decode my notice02

I owe the IRS

Explore payment arrangements, financial disclosures, penalty relief, and other resolution considerations.

Explore payment options03

I want penalties reduced

Relief may turn on compliance history, reasonable cause, documentation, and which penalty was assessed.

Estimate penalties and interest04

I have unfiled tax returns

Identify which returns may be required, which records are missing, and how to approach filing before collection escalates.

Triage the case05

I’m being audited, or I disagree

Examination scope, documents requested, issues under review, and whether an appeal or hearing right is still open.

Request a case review06

The IRS is taking collection action

Liens, levies, wage garnishment, bank action, enforced collection, and any remaining hearing rights.

The letter map

Every IRS collection letter follows a published sequence. Here's the map.

Find the letter you received to see what it is, what response window the IRS gives you, and what rights you hold at that stage. No countdown clocks, no fear pricing — the sequence is public, and so are your options.

First noticeEnforcement
CP14

The first bill

Response window: 21 daysSent: regular mailStep 1 of 6

What this letter is

The IRS's first statement that it believes you owe. It's a computer-generated bill, and the figure is frequently wrong in your favor — penalties that qualify for abatement, payments not yet credited, or a return that missed deductions.

Your response window

You have 21 days before the reminder cycle begins. Interest accrues from the original due date either way, so the number moves slowly, not suddenly.

Your options at this stage

Verify before you pay. You can dispute the balance, request first-time penalty abatement with a single letter, or set up a payment plan online in minutes. Every option in the entire sequence is available here, at its lowest cost.

The code in the corner tells you which deadline is running and what the IRS is actually asserting — and those deadlines are jurisdictional. Enter it here and I'll tell you what it means and what has to happen next.

Notice · CP14As printed
Balance due — first notice. The first bill for a balance the IRS says you owe on a filed return. It is the opening move, not a collection action.

Action needed

Deadline that matters
Pays-by date is ~21 days from the notice date. Interest and the failure-to-pay penalty keep accruing until it is paid.
If you ignore it
The account rolls into the collection notice stream (CP501 → CP503 → CP504) and penalties keep compounding.
Is it fixable / over-assessed?
Often the underlying number is right but the penalties are abatable (first-time abatement). Verify the balance matches your records before paying.
Typical resolution path
Confirm the balance, then either pay, set up an installment agreement, or dispute if it is wrong. Check penalty abatement first.
Notice · CP2000As printed
Proposed changes — underreporter (AUR). An automated proposal — NOT a bill and NOT an audit — generated when third-party forms (1099, W-2, 1099-B) do not match your return. It is frequently wrong or overstated.

Action needed

Deadline that matters
Respond by the date on the notice, usually 30 days. Missing it leads to a Statutory Notice of Deficiency (see Letter 3219 / "90-day letter").
If you ignore it
The proposed tax is assessed, then becomes a CP14 bill and enters collections. You lose the easy window to correct it.
Is it fixable / over-assessed?
High. The classic case: brokerage 1099-B gross proceeds counted as income with no cost basis. Reconcile basis and wash sales on a Form 8949 and the real number is usually a fraction of the proposal.
Typical resolution path
Agree, partially agree, or disagree in writing with documentation. Basis/8949 corrections resolve most trader and investor CP2000s.
Notice · CP2501As printed
Initial underreporter contact. An earlier, softer version of the CP2000 — the IRS is asking you to explain a mismatch before it proposes a specific tax change.

Action needed

Deadline that matters
Respond by the date shown (typically 30 days). Ignoring it usually produces a CP2000 next.
If you ignore it
Escalates to a CP2000 proposed assessment, then to a bill.
Is it fixable / over-assessed?
Same as CP2000 — mismatches are often basis or timing issues that resolve with documentation.
Typical resolution path
Respond with the explanation and records; head off the CP2000 entirely.
Notice · CP501As printed
Reminder — balance due. A reminder that a balance from an earlier notice (e.g., CP14) is still unpaid.

Action needed

Deadline that matters
Pay-by date on the notice; interest and penalty continue.
If you ignore it
Moves to CP503, then CP504 (intent to levy).
Is it fixable / over-assessed?
Still early. Installment agreements and abatement are readily available at this stage.
Typical resolution path
Pay, arrange a payment plan, or dispute. Do not let it march to CP504.
Notice · CP503As printed
Second reminder — balance due. A second, firmer reminder of an unpaid balance. Collection pressure is building.

Time-sensitive

Deadline that matters
Respond promptly. The next notice (CP504) carries levy language.
If you ignore it
CP504 (intent to levy state refunds and begin the levy process) follows.
Is it fixable / over-assessed?
Payment plans still straightforward; abatement still worth checking.
Typical resolution path
Resolve now — pay, installment agreement, or dispute — before levy notices begin.
Notice · CP504As printed
Notice of intent to levy (state refund). A serious escalation. The IRS states its intent to levy your state refund and warns it may levy other assets. It is not yet the final levy notice that unlocks a hearing.

Time-sensitive

Deadline that matters
Act within the time stated. This is the step before the LT11/Letter 1058 final notice.
If you ignore it
Leads to a final Notice of Intent to Levy (LT11 / Letter 1058) and the loss of easy options.
Is it fixable / over-assessed?
Getting into a payment plan or currently-not-collectible status generally halts levy action.
Typical resolution path
Contact the IRS or have a representative do it immediately; establish a collection alternative.
Notice · LT11As printed
Final notice of intent to levy + right to a hearing. The final Notice of Intent to Levy (also issued as Letter 1058). It unlocks your Collection Due Process (CDP) appeal rights — a critical, time-boxed protection.

Hard deadline — act now

Deadline that matters
You have 30 days from the notice date to request a CDP hearing (Form 12153). Filing timely generally pauses levy action and preserves Tax Court review.
If you ignore it
After 30 days the IRS may levy wages and bank accounts, and you lose the CDP hearing right (only the weaker equivalent hearing remains).
Is it fixable / over-assessed?
The 30-day CDP window is the single most valuable deadline in collections. Do not let it lapse.
Typical resolution path
File Form 12153 within 30 days and propose a collection alternative (installment agreement, OIC, or CNC). This is representation work — bring in an EA.
Notice · CP90As printed
Final notice of intent to levy (certain assets). Another form of the final levy notice with CDP hearing rights, historically tied to levies on federal payments and specific assets.

Hard deadline — act now

Deadline that matters
30 days from the notice date to request a CDP hearing (Form 12153).
If you ignore it
Levy proceeds and CDP rights lapse.
Is it fixable / over-assessed?
Same 30-day CDP protection as LT11 — use it.
Typical resolution path
Timely Form 12153 with a proposed resolution.
Notice · CP91As printed
Final notice — levy on Social Security benefits. Final notice that the IRS intends to levy a portion of Social Security benefits.

Hard deadline — act now

Deadline that matters
30 days to request a CDP hearing.
If you ignore it
Up to 15% of benefits can be levied.
Is it fixable / over-assessed?
Fixed-income taxpayers frequently qualify for currently-not-collectible status, which stops the levy.
Typical resolution path
Request the hearing and establish CNC or an affordable plan.
Notice · CP508CAs printed
Seriously delinquent debt — passport certification. The IRS has certified a large unpaid balance (indexed threshold, ~$62,000+ for 2024) to the State Department, putting your passport at risk.

Hard deadline — act now

Deadline that matters
No fixed hearing clock, but passport action can follow quickly. Reversal requires resolving or formally arranging the debt.
If you ignore it
Passport application/renewal can be denied and an existing passport can be revoked.
Is it fixable / over-assessed?
Entering an installment agreement or OIC generally reverses the certification (IRS issues CP508R).
Typical resolution path
Arrange the debt (payment plan/OIC) to trigger decertification; urgent if you travel.
Notice · CP49As printed
Refund applied to a prior balance. The IRS kept your refund and applied it to a past-due balance (an offset).

Informational

Deadline that matters
No action required if correct. Dispute promptly if the offset or the underlying balance is wrong.
If you ignore it
Nothing further, but an unverified prior balance may be incorrect.
Is it fixable / over-assessed?
Sometimes the prior-year balance itself is disputable; the offset is a signal to check it.
Typical resolution path
Verify the prior balance; dispute if the debt was already paid or is incorrect.
Notice · CP12As printed
Math-error correction — refund changed. The IRS made a math or credit adjustment and changed your refund. Often a credit (EITC, CTC, recovery rebate) recalculation.

Informational

Deadline that matters
You have 60 days to dispute a math-error adjustment before it becomes final and harder to reverse.
If you ignore it
The correction stands. If the IRS was wrong, you can lose the easy 60-day reversal window.
Is it fixable / over-assessed?
Math-error notices are sometimes wrong; the 60-day window is your cheap fix.
Typical resolution path
Agree, or dispute in writing within 60 days with your figures.
Notice · Letter 525As printed
General 30-day examination report. The examiner's proposed audit adjustments (30-day letter). You can agree or appeal within the IRS before it becomes a formal deficiency.

Time-sensitive

Deadline that matters
30 days to respond or request an appeal with the IRS Independent Office of Appeals.
If you ignore it
A Statutory Notice of Deficiency (90-day letter) follows, then assessment.
Is it fixable / over-assessed?
Appeals often produces a better result than the exam; the 30-day window is when it is cheapest.
Typical resolution path
Respond with documentation or file a protest to Appeals within 30 days.
Notice · Letter 692As printed
Request for consideration of additional findings. A follow-up examination letter offering a chance to respond to revised audit findings before they are finalized.

Time-sensitive

Deadline that matters
Respond by the date shown (commonly 15–30 days).
If you ignore it
Findings are finalized; a deficiency notice can follow.
Is it fixable / over-assessed?
Still inside the exam/appeals window — documentation can move the number.
Typical resolution path
Respond with support or escalate to Appeals.
Notice · Letter 3172As printed
Notice of federal tax lien filing + CDP rights. The IRS filed a public lien against your property for unpaid tax and is notifying you of your CDP appeal rights on the lien.

Hard deadline — act now

Deadline that matters
30 days (plus a short mailing window) to request a CDP hearing regarding the lien (Form 12153).
If you ignore it
The lien stands, damages credit, and attaches to property; CDP lien rights lapse.
Is it fixable / over-assessed?
Lien withdrawal/subordination and payment arrangements are negotiable, especially via a timely CDP request.
Typical resolution path
File Form 12153 for the lien and pursue withdrawal or a collection alternative.

Before responding

Protect the deadline and preserve the facts.

01

Do not ignore the notice

Many notices include response deadlines or appeal rights that can expire.

02

Do not assume the IRS is correct

Notices may be based on incomplete, mismatched, duplicated, or missing information.

03

Do not send documents blindly

A response should address the exact question and tax period the IRS is reviewing.

04

Preserve every page

Keep the complete notice, envelope, prior correspondence, returns, and supporting records.

05

Confirm the deadline

Identify the response, payment, hearing, or appeal date before choosing a path.

06

Get help early

Representation is generally easier before rights expire or enforced collection begins.

Frequently asked questions

Clear answers without unrealistic promises.

Should I call the IRS myself?

You can, but first understand the notice, issue, and information you are prepared to provide. Statements made during a call may become part of the case history.

What happens if I ignore an IRS notice?

The IRS may issue additional notices, assess tax, limit appeal rights, or begin collection action depending on the issue.

Can TaxSpectra speak to the IRS for me?

When properly authorized, an Enrolled Agent may communicate with the IRS on your behalf within the scope of the engagement.

Can I set up an IRS payment plan?

Possibly. Eligibility and terms depend on the balance, filing compliance, financial information, collection status, and other facts.

Can penalties and interest be removed?

Some penalties may qualify for relief. Interest is generally more limited and often changes only when the underlying tax or penalty changes.

What if I have several years of unfiled returns?

First identify which returns are required, gather records, and determine whether the IRS prepared substitute returns or started collection.

What should I bring to an IRS case review?

Bring the complete notice, prior correspondence, relevant returns, payment records, financial information, and documents connected to the issue.

Does hiring a representative guarantee a lower balance?

No. Representation improves organization, communication, analysis, and advocacy, but outcomes depend on the law and the facts.
